49 22nd Deluxe Sedan Locks

Hello,

I have a question about the door locks on my Deluxe. Both are broken, keys turn but when I pulled off the drivers door card to fix the window I found the square rod sitting on the bottom of the door. I read through the manual and the threads it didnít specifically see what I was wondering, and I donít want to brake anything because the appearance of locks is better than nothing!

My question is, using the needle technique or similar, can I (or a locksmith)remove just the broken tumbler and then slot in a working one (without removing the whole latch assembly)? If that is the case, has anyone identified specifically a tool or needle that fits/works?

Attached is the picture of the broken rod.

Good question about the Ďneedleí. As I remember the square rod is attached to the lock cylinder with a joint that allows quite a bit of flexibility . . . make that too much flexibility. Iíve never attempted the Ďneedleí technique, but I would suspect it starts with pushing a needle from the outside of the car through the door panel/card, noting the location, and then at the same location pushing the needle from inside the car back through the latch. I believe the square rod has a dimple in the end that the needle will index into. The lock & rod and the needle are moved into position as one assembly, with a bit of teasing as the rod enters the latch.

Now hereís the good news, if you Ďzip tieí (use a real small one) the stainless rectangular stock that reinforces a wind shield wiper blade to the square rod you can manipulate the rod as it approaches the latch mechanism. Once the rod engages you will still have enough room to extract the rectangular stainless piece. Youíll end-up with a Ďzip tieí around the rod, but no needle hole in the door panel/card.
If the door panels/cards are removed you should succeed without the use of a needle.

Am I missing something here? If the door card is already off there is no need for elaborate procedures--just bring the shank into the latch as the tumbler is inserted into the door. Been quite a while since I have done it but I remember getting my hand up in there to guide it in.

Ok, I think I was looking to confirm that the tumbler can be removed and I erred by hand, and there wasnít some reason why the procedures needed to be used for alignment of the shaft or anything. Most threads are about more complicated situations (door permanently locked, broken latches, etc). I didnít want to try pushing the lock out by hand and end up creating a problem.

Finally got around to the locks, of course it didnít go as planned. First I realized that I needed to grind down the end of the new shank as mine was square up to the end. Once that was done, I thought it would just slide in but the angle of the tumbler is too severe for the shank to fit in the latch and the lock to sit flush. I may have to order another set of locks and keys because the eBay ones I have donít have enough angle.

Why wouldnít they just make the tumbler directly across from the latch?!?

So Iíve heard there might be small u-joints to install that rectify this issue? Can someone confirm this for me before I drop unnecessary $$ on another set of locks?

Yes, there should be a universal joint in the 22nd and 23rd Series door locks as well as the stepped down lock end on the shaft.

It looks like what you have is a lock for the 20th and 21st series which did not use the universal joint and had a square end on the shaft.

Breakage of the small universal joint is a common reason for failure of the 22nd/23rd Series door locks.

Great, that is very helpful! It seems like Iíll need to just buy a new kit with the joints and stepped down shaft.

Thanks a bunch!

No idea what a lock kit would cost or if they are available to convert the shafts on locks you have but If there is a lot of expense for a kit and you have the old locks and there is enough room to add a commercial U joint, you might be able to do the job fairly inexpensively.

I measure the shaft on a 47 lock to be 5mm and imagine the 22-23 is probably the same. Amazon has an assortment of various size miniature U joints in that range made for robotics and RC models. If the length of the U joint will fit in the space between the lock and the latch assy you could use a portion of the old stepped down shaft from the old lock by cutting it to size and then cutting a length off the shaft of the new lock in order to install one of the miniature universal joints near the cylinder. That arrangement might be stronger than the original pot metal U joint assy. Amazon has other style joints besides the one I show.

Thanks Howard! I was about to get new ones but I think Iíll give that a try to see how it goes. Given itís a daily driver in the NE I also like the idea of avoiding pot metal joints and opting for something a bit stronger, at least for unseen door innards. Iíll report back about how it goes.
